IMPROVEMENT IN DETACHABLE OVENS.

Specification forming partof Letters Patent No. 48,200, dated June 13, 1865.

t Fig. 2 shows the inside form ot' the oven and the principle of the draft.

This detached oven can be made either of sheet or cast iron, and isso constructed that it can be attached to the top or back part of any cook, air-tight, or lamp stove by means of either round or oval Hues, thereby connecting the oven to the stove and pipe, which permits the heat and smoke of the stove to pass round the draft of the oven one and one-half time before entering the stove-pipe, and without incurring any extra expense for fuel.

To support the oven on any stove, movable jointed legs can be used adapting it to any height.

The boiler holes and Hues have covers which are made to slide or swing round and Ht close, so as to permit of their being used whether the oven is attached to the top or back part of a stove.

The oven or baking-chamber (shown at O in the drawings) is provided with a door, D, and has affixed to the middle of each side of its interior surface a ledge, a, for supporting a shelf Furthermore, the oven is surrounded on its four sides by a Hue, A, which at one end opens into another Hue, G, that encompasses the first Hue, A. The Hue G has a pipe, F, leading out of the middle of lits bottom, and it also has another such pipe, F, leading from the middle of its top, the same being as exhibited in Fig. 2. In the lower part of' the Hue G there is one damper, D, and in the upper part of such Hue there are two other dampers, d d, which are arranged relatively to the upper pipe, F', and a hole or passage, e, in inanner as represented in the said Fig. 2. Thesaid hole or passage eopens out of the Hue A. By closing the dainpers D d d the smoke and vol- By my arrangement, therefore, of dampers and Hues I am enabled, by throwing the smoke 4through the external Hue only, to utilize most ot` its heat for heating the apartment in which the oven may be situated. I can also cause the smoke to pass through both the tlues, and thus while warming lthe apartment heat the oven sufficiently for baking purposes. Furthermore, when the smoke goes through the outer Hueonly, `the inner Hue serves to insulate the heat thereof from the oven to such extent as not only to prevent its sides from being injured thereby, but to cause them to be only moderately heated, whereby the oven may be used as a simple Warming-chamber.

There are boiler-openings f f f f in one end and one side ot the outer case of the iiues, the covers of these openings being shown at B B B B in Figs. 1 and 2. These, with the ledges a a a a, applied to the four sides of the oven, are to enable a shelf to be arranged in themiddle of the oven and one or two of the boilers to he heated, whether the oven be used with its longer sides either horizontal or vertical, as circumstancesrmay require.

' I claim 1. The combination and arrangementof the oven O, the two Hues A G, the induction and eduction pipes F F, the opening e, and the dampers D cl d, the whole being substantially as specified.

2. In connection with the oven and its Hues, arranged as described, the four ledges a a a a, arranged and applied to the four sides of the interior of the oven.

3. In connection with the oven and its Hues, arranged as described, the boiler-openings ff ff, applied to one end and one side of the outer Hue-case, for the purpose specified.
